2-[(1E,4E)-2-(4-Methoxy-phen-yl)-3H-benzo[b][1,4]diazepin-4-yl]phenol

The title compound, C22H18N2O2, is a biologically active 1,5-benzodiazepine derivative, containing three planar six-membered rings and one nonplanar seven-membered ring. The six-membered rings A (phenol), B (fused benzene) and C (methoxyphenyl) are oriented with respect to each other at dihedral angles of 39.22 (2) (A/B), 87.31 (3) (A/C) and 54.42 (3)° (B/C). The seven-membered ring adopts a near-boat conformation. In the crystal structure, intra-molecular O - H⋯N and inter-molecular C - H⋯O hydrogen bonds are present.
